First Thanks to those of you that replied to my previous thread
"Upgrade from 350 & 100-400 "
This question is about drop in filters
I see that Canon's prime lens of longer focal length and larger physical size use a drop in filter.
I am used to using a UV or Skylight filter on the front of the lens to protect it from accidental damage.
I don't use any other filters perfering to use photoshop.
What is the idea behind the drop in filter?
I presume it is smaller diameter and therefore cheaper to produce / purchase ?
Is it used as well as or instead of a filter on the front? if instead off is it "just" a case of take extra care not to damage the front of the lens?
